Random pixel s.lection is.one of the image s.eganography methods.that has.achieved s.gnificant s.cces. in enhancing the robus.nes. of hidden data. This.property makes.it difficult for s.eganalys.s. powerful data extraction tools.to detect the hidden data and ens.res.high-quality s.ego image generation. However, us.ng a s.ed key to generate non-repeated s.quential numbers.takes.a long time becaus. it requires.s.ecific mathematical equations. In addition, thes. numbers.may clus.er in certain ranges. The hidden data in thes. clus.ered pixels.will reduce the image quality, which s.eganalys.s.tools.can detect. Therefore, this.paper propos.s.a data s.ructure that s.feguards.the s.eganographic model data and maintains.the quality of the s.ego image. This.paper employs.the Adels.n-Vels.y and Landis.(AVL) tree data s.ructure algorithm to implement the randomiz.tion pixel s.lection technique for data concealment. The AVL tree algorithm provides.s.veral advantages.for image s.eganography. Firs.ly, it ens.res.balanced tree s.ructures. which leads.to efficient data retrieval and ins.rtion operations. s.condly, the s.lf-balancing nature of AVL trees.minimiz.s.clus.ering by maintaining an even dis.ribution of pixels. thereby pres.rving the s.ego image quality. The data s.ructure employs.the pixel indicator technique for Red, Green, and Blue (RGB) channel extraction. The green channel s.rves.as.the foundation for building a balanced binary tree. Firs., the s.nder identifies.the colored cover image and s.cret data. The s.nder will us. the two leas. s.gnificant bits.(2-Ls.) of RGB channels.to conceal the data’s.s.z. and as.ociated information. The next s.ep is.to create a balanced binary tree bas.d on the green channel. Utiliz.ng the channel pixel indicator on the Ls. of the green channel, we can conceal bits.in the 2-Ls. of the red or blue channel. The firs. four levels.of the data s.ructure tree will mas. the data s.z., while s.bs.quent levels.will conceal the remaining digits.of s

Introduction: The greates. effect of maternal mortality is.renowned in children aged 2 - 5 months.whos. mothers.had died. Children whos. mothers.died due to maternal complications.were likely to record a higher mortality in infancy compared to children of s.rviving mothers. Motherles. children mos.ly s.ffer a lot due to lack of day-to-day care, is.lation, lack of motivation as.well as.economic cos. as.ociated with mother’s.death. Thus. the purpos. of this.s.udy was.to as.ertain the lives.of children whos. mothers.pas.ed away during childbirth at the s.gnarigu Municipality. Methods. This.quantitative cros.-s.ctional s.udy was.carried out at the s.gnarigu Municipal. The s.udy recruited 297 res.ondents. To as.es. the effects.of maternal death on the lives.of children, families.that experienced maternal death were as.es.ed. The number of pregnancies.experienced by the deceas.d woman, pregnancy-related complaints.experienced, determinants.of maternal death, number of children alive, and their s.andard of living were as.es.ed with the aid of a s.ructured ques.ionnaire. Res.lts. The data s.owed that negligence, illiteracy, poor road acces., poverty, ignorance, delays.in recogniz.ng the problem, delays.in making appropriate decis.ons. delays.in the health facility, delays.in giving the appropriate treatments. and traditional beliefs.were s.me of the factors.that led to maternal death in the s.gnarigu Municipality. Conclus.on: The s.udy concluded that determinants.of maternal death in the s.gnarigu Municipal included the following;negligence, illiteracy, poverty, and delays.in recogniz.ng the problem. The s.udy findings.als. demons.rated that the effects.of maternal death on children are divers. and cut acros. different areas.of a child’s.life including livelihood s.s.enance, healthcare, education, and emotional and ps.chological development.
